' This invention relates to a pressing machine. An object of theinvention is to provide a machine of the character described which isuseful in the manufacture of garments, and particularly useful in theformation of the garment pockets.

A particular object of the invention is to provide a pressing machinedesigned for the purpose of pressing back the flaps of material on eachside of the pocket slit preparatory to sewing the flaps permanently tothe material of the garment in the manufacture of clothing.

A further object of the invention is to provide a pressing machine ofthe character described that may be quickly and easily manipulated, thatis, of simple construction, accurate in operation, and which is verydurable in use.

With the above and other objects in view, the invention has particularrelation to certain novel features of construction, operation, andarrangement of parts, an example of which is given in thisspecification, and illustrated in the accompanying drawings, wherein:-

Fig. 1 shows an end view of the machine.

Fig. 2 shows a plan view of the work-receiving platform.

Fig. 3 shows a plan view of the slitted fabric to'be operated on by themachine.

Fig. 4 shows a plan view of the fabric illustrating the pocket flapsfolded back in position for sewing.

Fig. 5 shows a fragmentary cross-sectional view showing the pressureplates in position to receive the fabric to be operated on.

Fig. 6 shows a cross-sectional view illustrating the pressure plates inactive position.

Fig. 7 shows a perspective view of one of the pressure plates.

Fig. 8 shows a longitudinal sectional view illustrating the pressureplates in inactive, or workreceiving position, and

Fig. 9 shows a similar view showing the plates in active position.

Referring now more particularly to the drawings, wherein like numeralsof reference designate the same parts in each of the figures, thenumeral I designates a table which is supported on suitable corner legs2. Secured on this table is a supporting framework preferably composedof the U-frames 3, 3, the cross-bar connecting the upstanding arms ofthe frames being bolted on to the top of the table, as illustrated inFig. 1, said U-frames being suitably spaced apart, as illustrated inFigs. 8 and 9.

On this framework is the work-receiving platform 4 having the centrallongitudinal slot 5 therethrough. Each U-frame 3 is provided with acentral upstanding rod 6, the lower ends of the rods being supported onthe cross-bars of the U-frames 3 and their upper ends being anchored tothe platform 4 above.

There is a longitudinal yoke I whose ends are provided with thevertically aligned end bearings 8, 8, which slide on the correspondingrods 6.

There is a treadle 9 pivoted, at one end, to a cross-bar II] which issecured to the legs 2 at one 10 side of the table. A connecting link IIis pivoted, at its lower end, to the treadle 9, and this link isfastened at its upper end to the yoke I. The link may be formed ofsections bolted together, as shown in Fig. 1, thus providing foradjustments of the link in length.

Secured on opposite sides of the yoke I are the bearings I2, I3, thecorresponding bearings at each end of the yoke forming a pair. In thebearings I2, there is a rod I4, one end of which is turned outwardly atright angles to the rod, and extended across the yoke forming the armI5. In the bearings I3, there is a rod I6, one end of which is outwardlyturned at right angles to said rod I6 and extended across the yokeforming an arm II, the arms I5 and I! being arranged at opposite ends ofthe respective rods I4 and I6, as more clearly illustrated in Figs. 1,8, and 9.

Flexible connecting members I8, I8,are connected at their upper ends tothe free ends of the arms I5, I1, and at their lower ends to the treadle9. The rod I4 has the upstanding fingers I9, I9, secured thereto and therod I6 has similar upstanding fingers 20, 20, secured thereto.

' A pair of levers 2|, 2|, are pivotally connected at their lower endsto the upper margin of the yoke I on one side, and a pair of similarlevers 22, 22, are pivoted at their lower ends to the upper margin ofthe yoke I on the other side, said levers 2I and 22 being in alignmentwith the corresponding fingers I9, 20. There are the oppositely arrangedpressure plates 23, 24, which are similar in shape and construction, andone of which is illustrated in detail in Fig. 7. These pressure platesare arranged to Work through the slot 5 of the work platform 4 in amanner and for a purpose hereinafter to be described.

The ends of the pressure plates have the extended pintles 25 which ridealong the" arcuate tracks 26 that are formed in the depending flanges 21carried by the underside of the work platform 4 and secured thereto. Theupper, or free, margin of each pressure plate is overturned atapproximately a right angle to the 'main body of the plate forming thelips 28, 28,

ing fabric of the pocket being formed.

which work through the slot 5, and the upper ends of the levers 2|, 22,are pivotally connected to the other margins of the respective plates.

Pull-springs 29, 29, are attached, at their outer ends, to thedownwardly turned margins 4', 4', of the work platform 4, and the innerends of these springsare connected to the brackets 30, 30, which areattached to the outer sides of the respective levers 2|, 22. A coilspring 3| is connected at its lower end to the treadle 9, and at itsupper end to the table I, and the coil springs 32, 32, are connected attheir lower ends to opposite sides of the link H, and at their upperends to said table.

These springs 3|, 32, normally hold treadle 9, as well as the link I land yoke I in elevated position, and when in this position the links 2|,22, will be held in their outward position, as shown in Fig. 5, by thesprings 29, 29, with the pressure plates 23, 24, lying closely againstthe underside of the work platform, and the lips 28, 28, projectedvertically through the slot 5. The underside of the platform 4 isprovided with indentations 33 which provides spaces for hingesconnecting the levers 2!, 22, to the pressure plates, as illustrated inFig. 5, so that the main body of each plate may lie closely against theunderside of the work platform.

When in this position, theslitted fabric shown in Fig. 3 may be placedon the work platform with the lips 28 projected upwardly through theslit 34. The treadle 9 may then be depressed, pulling the arms l5, I1,downwardly and operating through the link II to pull the yoke 1downwardly also. As the arms l5, H, are moved downwardly, thecorresponding rods l4, [6, will be partly rotated, carrying the freeends of fingers I 9, 28, into engagement with the outer sides of thecorresponding levers 2|, 22, and forcing said levers inwardly intoapproximately parallel relation, as shown in Fig. 6. This will cause theouter margins of the pressure plates 23, 24, to swing downwardly andinwardly carrying said pressure plates into approximately parallelrelation, as shown in Fig. 6, and swinging the lips 28, 28, outwardly,overturning the flaps 35, 35, of the fabric, and pressing said flapsdownwardly-into folded position against the surround- Underneath thework platform around the slot 5, there is an electrical heater 36 whichis connected with a source of electrical supply through the wiring '31whereby the work platform is heated opposite the folded fabric. Thepressure is applied for a suilicient length of time to properly creasethe fabric to maintain the flaps in place until they are permanentlysewed. Upon release of the treadle 9, the springs 29, 3|, 32, willreturn the parts to their original, or inactive position, and the formedgarment pattern may be removed and another substituted for it, and theoperation repeated.

The drawings and description disclose what is now considered to be apreferred form of the invention by way of illustration only while thebroad principle of the invention will be defined by'the appended claims.
